Mary Poppins is a strain of cannabis created and cultivated by Mykilo Sosa, an activist and connoisseur who currently resides in Northern Indiana. Its true genetics remain a secret, but there are elements of Hashplant (Sensi Seeds), LSD Lifesaver x Deisel Sour(Bog Seed Co.), and various others Mr. Sosa has grown in the past.

Mr. Sosa, why do you call this particular strain of cannabis Mary Poppins?
Well, because its that super-cali-fragilistic-expiali-doja; like some of that real Cali shit!

At the completion of a blowjob, the recipient takes a spoonful of sugar to mix in with the "jizz" (ejaculate) in the givers oral cavity (mouth) to help the "medicine" go down; typically done to augment the taste.

Hey Bob, Jamarius has given Caitlin so many Mary Poppins that she has now three cavities.

2. Those stupid girls who look good in a fucking sack and can play in mud and look like a beauty queen. They get the promotions, the pay rises and the gorgeous clothes.
You secretly want to stab these people in the back on the head with scissors.

2. Oh fuck me! Leah is such a Mary Poppins I want to stab her in the back of the head with scissors
